Ashton Kutcher files for divorce from Demi Moore

On Friday, Ashton Kutcher, 34, filed paperwork for divorce from Demi Moore, 50, in Los Angeles Superior Court, reports People.com, citing irreconcilable differences. The Two and a Half Men star isn't seeking any spousal support nor is he asking the court to deny Moore any. The documents also show that because the couple, who married in 2005, had no children together, child support and visitation are not an issue.

"As a woman, a mother and a wife there are certain values and vows that I hold sacred, and it is in this spirit that I have chosen to move forward with my life," Moore said at the time of the split, which followed a rush of tabloid attention alleging that Kutcher cheated on Moore with a 22-year-old in September 2011.

A year ago, Kutcher put a more positive spin on their decision to part: "I will forever cherish the time I spent with Demi. Marriage is one of the most difficult things in the world and unfortunately sometimes they fail."

In happier times, the two were red carpet fixtures. Moore named her Twitter account @mrskutcher, and the couple regularly posted public love notes to each other. In a rare joint interview in 2011 with USA TODAY discussing their campaign to end sex trafficking, the couple were affectionate with each other, finishing each other's sentences and never sitting more than a few feet apart.

Earlier that year, Kutcher sat with USA TODAY while promoting his film, No Strings Attached, and spoke warmly of his relationship with his then-stepdaughters, Rumer, Scout and Tallulah. "Tallulah was like, 8 when (Demi and I) first started dating. So I've got like the 8-to-20 thing on lock."

"Your best teachers are your parents anyway," Kutcher said of parenting. "You take the 'best of' from your parents and you try to eliminate the 'worst of' from your parents. It's completely a learn-on-the-job thing."

Since their separation, both stars have since moved on. Kutcher has been dating his former That '70s Show co-star Mila Kunis, 29, since April. Moore recently dated Vito Schnabel, 26, the son of famous artist Julian Schnabel.

Kutcher has not referenced filing for divorce on Twitter, but on Thursday he tweeted that "2012 has been the year for new and bigger things," linking to a blog post that mentioned his excitement over playing Steve Jobs in the upcoming biopic, jOBS. Moore's Twitter account has been largely silent since late November, when she tweeted about putting an end to human trafficking. Her next film, Very Good Girls, is due in 2013.
